2.添加dm9000的代码，在arch/arm/mach-s3c64xx/mach-s3c6410.c

添加头文件

#include <linux/dm9000.h>

添加初始化代码。分配资源

/*
dm9000
add by fatfish
*/
/* DM9000AEP 10/100 ethernet controller */

static struct platform_device *smdk6410_devices[] __initdata中添加

static void __init smdk6410_machine_init(void)中添加

smdk6410_dm9000_enable();
